Supporting this proven projectile is Shell Shock Technologies’ NAS³ casing, which ensures ultra-consistent geometry, optimal chamber alignment, and uniform wall thickness. These attributes minimize recoil, reduce inconsistencies, and tighten groupings, giving hunters the reliable accuracy they depend on. Built from a nickel alloy body and stainless-steel head, NAS³ casings are stronger than brass, resistant to corrosion, and designed to withstand the rigors of extreme hunting environments. They are also up to 30 percent lighter than traditional brass cases, reducing fatigue in the field and allowing hunters to carry more ammunition with less weight. The visible discoloration on each NAS³ case neck is the result of heat annealing, a process that improves bullet grip, enhances neck tension, and increases consistency shot after shot. Combined with SST’s eco-friendly, lead-free design, hunters can count on cleaner barrels, reduced fouling, and environmentally responsible performance without sacrificing results. “The introduction of our 308 NAS3 PROGRADE Ballistic Tip Ammo represents a major step forward in our commitment to innovation, performance, and reliability,” said Peter Foss, Managing Partner and CEO of Shell Shock Technologies. “By combining our advanced NAS3 casing with Nosler’s proven Ballistic Tip technology, we’ve created a cartridge that gives hunters the confidence they need in the field: accuracy at extended ranges, flat velocity, and the stopping power to make every shot count.” Delivering a muzzle velocity of 3,050 feet per second, superior accuracy, reduced recoil, and flawless cycling, the 308 NAS³ PROGRADE gives hunters the flat trajectories and stopping power needed for elk, deer, and other challenging pursuits. Hunters will find it to be the ultimate ally in achieving consistent results. Shell Tech 308 NAS3 PROGRADE Ballistic Tip Ammunition Specifications: |
